You need the kernel line to point to Xen.  Include the vmlinuz as a "module" 
line, and include the initrd as a second "module".

Grub can't boot the Xenified vmlinuz directly, but it can boot Xen and pass 
the Linux kernel to Xen as a module.

Dave: Skateboards have wheels.
Mark: My wheel has a wheel!
